Description

Beginning with definitions of such basic terms as cryptanalysis, encryption, and decryption, this introduction from the Intelligence and Counterintelligence series emphasizes the point that cryptography is now a part of everyday business, not limited to espionage and the military. The narrative explains how various ciphers are constructed, from the simplest to the most complex, then covers basic concepts and types of cryptanalysis. After a short overview of cryptology through history, the survey concludes with a look at the development of modern electronic cryptology. Facts and concepts are well organized and clearly presented, but sources are not cited. Charts, photographs, and sidebars add visual variety, but this study is best suited for the serious student, not the casual browser. Back matter includes a glossary, a bibliography, and an index. Grades 9-12. --Linda Perkins
